Mass Effect 3 with all the DLC, FOV fix and some HD mods. The FOV messes up the cutscenes (you can see all the assets left lying out of frame, like multiple versions of the characters waiting for a new camera angle to do their scene) but I don't mind.
Also got Red Faction 3 with a mod that makes the buildings collapse a little more realistically. My car swerved, drifted, rolled and went straight through a buildings wall and exploded. Shockwave blew out the windows, walls shudder and it all came down.
